Dear All, For some reason. I was trying to put a test on the Win2k8 R2 srv AD Dc into a Samba AD Dc.. And found that there are some problem with the network... possible the sysvol replicating or etc?? But what I notice is that some of my WinXP don't found their GPO Map drive anymore... So to cut the question short... How can I remove win2k8 from samba AD DC... Any guide? sorry as this is my 1st install on win server... so I have no knowledge of it and might do wrong... Thank You.
